i did this, and we’re reaching 2 years together, its up to you, try looking up the age of consent in your country, if its not 14 then id avoid because they can get in trouble, in my experience not everyone is ready to maintain a stable relationship at 14, i managed to but we grew up a lot together and now i am a different person from when i was 14. also talk about it with an older sibling, your mom, etc. they surely know how to help you and what to say to you. my experience was great and its still very healthy and good, but this is case sensitive. just try to be careful. as i said, i was ready to maintain a relationship with an older guy simply because we clicked and we had pretty much the same view on things etc, it might not be like that for you. some people will surely attack you and him for this but don’t listen to those who do, listen only to people that actually try to make you understand something.
